This filter is in excellent condition. I finally moved to a dark sky area and no longer need this filter.
I will also conside a trade for a quality 1-1/4" IR blocking filter + $$$. PayPal prefered.
#911B: Threads onto the rear cells of Meade LX-series mirror-lens telescopes and onto Meade ED Apochromatic Refractors (using the Universal Thread Adapter), as well as to the rear cells of other Schmidt-Cassegrain brands. In this way the telescopes are converted into a basic “nebular mode,” for visual observing or for photography with the T-Adapter or Off-Axis Guider. Clear aperture is 36mm.
